final A4000 Measurements (Frequency Response Graphs) and Comparisons with Etymotic ER2XR

I had posted measurements (frequency response graphs) earlier for final A4000 based on my old rig. Here are the latest measurements based on v1.0 of my IEM Measurement Rig.

final A4000 Left and Right Channel Frequency Responses

3 samples each of the left and right channel. For each sample I remove and re-insert the IEM.

Etymotic ER2R Measurements (Frequency Response Graphs)

These are the first measurements from v1.0 of my IEM Measurement Rig.

final A4000 measurement (frequency response graphs) and comparison with Etymotic ER2XR

Please disregard this post and see the latest final A4000 measurements (frequency response graphs) and comparisons with Etymotic ER2XR using v1.0 of my IEM Measurement Rig.

These measurements are made on my DIY IEM measurement rig and are not accurate, and don’t necessarily represent what you might hear, especially before 60 Hz (huge sub-base roll-off) and after 10 kHz (and maybe even after 3 kHz as my ER2XR graph is very different compared to Crinacle’s post that). You can use it just to get a comparative idea, hence the comparison with ER2XR to give you a point of reference. Improving the rig is an ongoing process.

Here is Crinacle’s ER2XR graph for reference

It looks like final went with the mids to bass rise like in the E series and the highs of the A8000 on A4000.
